Low-temperature sintered black alumina ceramic
The invention relates to a low-temperature sintered black alumina ceramic. Products such as a packaging tube shell, a substrate, a substrate and an LED display screen prepared from the material are applied to an electronic integrated circuit for shading. The ceramic material is prepared from the following raw materials: aluminum oxide, cobalt oxide, titanium dioxide, silicon dioxide, manganese oxide, lithium carbonate, bismuth oxide, vanadium pentoxide and the like. The components are sintered into the black aluminum oxide ceramic through solid-phase reaction procedures of burdening, primary ball milling, granulation, forming and bowl-filling sintering. The ceramic material can be compactly sintered at a low sintering temperature of 1280-1320 DEG C/3h, is energy-saving and environment-friendly, has a low dielectric constant and high mechanical strength, particularly does not contain harmful elements such as heavy metals, and meets the ROHS (Restriction of Hazardous Substances) requirements of the International Electronic Union.
本发明涉及一种低温烧结黑色氧化铝陶瓷。其制备的封装管壳、基片、基板、LED显示屏等产品应用于遮光用的电子集成电路中。该陶瓷材料的制造原料含有：氧化铝、氧化钴、二氧化钛，二氧化硅、氧化锰、碳酸锂、氧化铋、五氧化二矾等组分；将上述组分经过配料、一次球磨、造粒、成型、装钵烧结的固相反应工序烧结成黑色氧化铝陶瓷。本发明具有较低的烧结温度在1280‑1320℃/3h就能致密烧结、节能环保、低介电常数，高机械强度，特别不含重金属等有害元素，符合国际电子联盟ROHS要求。
